What Now? AdBlue in the Diesel Tank in Llantwit Major

What to do about AdBlue in a diesel tank depends on one thing more than any other: whether the engine has been run since it went in. Not started so far? Then keep it like that, whether the car sits — Llantwit Major or Caermead. Phone 0333 366 0103 with your ignition and engine both off. In Llantwit Major, such a case is typically drained and flushed on the spot. If it's run, stop as soon as it is safe then switch off. A bigger job, then, but the same opening move.

Wherever in The Vale of Glamorgan it took place, one of the cases below matches yours.

At the pump in Llantwit Major: AdBlue in a diesel

The cap you unscrewed was the wrong one — and you just notice it as you're standing at the pump, bottle or the nozzle in your hand. Anywhere around Llantwit Major, then — Esso, another forecourt nearby, or anywhere else close by.

The point: of all places to notice, the forecourt is the best. Only that tank holds AdBlue; no component past it has drawn it in.

Next: resist the urge to fire it up only to free up the pump. Get the staff to lend a hand rolling it to a bay, hold on to the bottle, then phone us from there. The equipment is explosion-proof and fine on a busy forecourt, so a vehicle that can't be pushed away gets drained where it is at the petrol pump.

At home in Llantwit Major with AdBlue in your diesel tank

For days the dash had been warning you. A bottle bought at the shop, emptied in on the drive — and it's just by the bin that the cap got a second look. Driveways near The Strand get it as much as anywhere.

Meaning? As long as your vehicle has not been driven since, it is second to the pump case. AdBlue doesn't mix with diesel; it sinks to the bottom of the tank and waits there. Overnight does not change that.

Next: stop any early-morning drive by putting the keys in the house, then ring us. Our technicians drain it on your drive, whether that is in Llantwit Major or out in West-end Town. Even at night, our pumps stay quiet enough for a residential street.

On the road in Llantwit Major with AdBlue in a diesel

Lumpy running, smoke, lost power or a lit dashboard started a mile or two beyond the top-up. Anywhere on Commercial Street or else on the road to Cardiff — under 15 miles away.

Meaning? Your fuel pump has taken the AdBlue up. Past the filter, along the pipework, and — the more the distance — deeper into the injection pump and every injector. It travels further with each mile covered and every restart.

Next: find a safe spot, stop, then turn the motor off. Service stations further on are too far: on the M4, under 10 miles out of Llantwit Major, take the first junction. Starting it again to test gets nothing — AdBlue never clears itself. About what distance did it go? Say so when you phone.

Hire, lease or company car with AdBlue in the wrong tank

A week back, it was unknown to you. On your own car, AdBlue is absent or somewhere else. On this one, the cap is just by your diesel inlet — news to you. Across The Vale of Glamorgan, nobody is safe from it.

What it means: the same as the scenarios above, depending on whether it has run, with one more stage. Plenty of hire and company contracts want the owner to approve work on the vehicle.

Do this: rental firm or fleet manager first, us second, because settling it early saves time. If you're stranded in the car park outside the nearest station, or by Old Guild Hall/Town Hall, while you wait for an answer, leave your car off.

Unsure about AdBlue in the diesel tank in Llantwit Major?

Now and then, "I think so" is the most you can truthfully say. Which cap was taken off, you can't recall; meanwhile the bottle feels less than expected, and a whiff of ammonia hangs by the filler. Perhaps it happened in a hurry at the school gates at the local primary school, or on a friend's drive in Boverton.

Put simply: a spill round your filler does the motor no harm. Once it's inside your diesel tank, though, it does. Turning on the vehicle will not tell you which, and if there is AdBlue in the tank it will suck it in.

Next: act as though it got in, and keep the motor off. Call us and describe what you saw; we would rather check a tank that turns out free of AdBlue than drain one that has already been run.

What each AdBlue drain in Llantwit Major has in common

The work begins the same way, whichever your case. Forecourt, drive, The King's Head's car park or a road beside St. Illytd's — the van comes to your vehicle, and three answers follow: what liquid, what quantity, and whether it ran. Those replies determine the work, and you get the price on the phone, before anyone heads out.

Then your tank is cleared and your system rinsed thoroughly, which counts more with AdBlue than with petrol: AdBlue crystallises and is corrosive to some of the metals in a fuel system, so it doesn't rinse out on its own. Last come your filter, flushed or replaced as needed; fresh diesel; and a test of the vehicle. Never started? In that case roughly half an hour once we are there is most jobs.

Last, we start the car. We confirm it runs properly on fresh diesel before leaving. If it is caught quickly, the car very rarely has permanent damage, and the entire job happens where it is. Nothing is taken upfront, payment happens on the day, and you get what your insurer wants: an engineer report plus a VAT invoice. It is worth knowing: many insurers include misfuelling cover, so a quick look at your documents as we travel pays.
